I noticed this Kickstarter project the other day which I think looks amazing. The project is creating laser-cut wood pieces with which you can make dungeons or villages for table top play.

Some of the pieces attach to the base plate(s) and the rest of the items slot together so it’s completely modular and can be taken apart too. Floors and roofs can be removed too so you can use the inside of the buildings. Whilst primarily for role-playing and table top games, I think they’d be great as the board for a board game too.
